Abstract:
Objective To investigate a new method of improving design of the skin flap pedicled with descending hranch of lateral femoral circumflex artery,in order to increase the accuracy of preoperative Doppler location.Methods Six fresh cadavers underwent a whole body,intra-arterial injection of a lead ox- ide and gelatine preparation.Observe the perforators of anterolateral thigh by dissection,measured their diam- eter;course,branches and location for there were showed up by angiography and photography.A specific pro- gram,3D-doctor,was used for the detection of the regions of interest in angisome and its 3D-reconstructive.In addition to the average area supplied by a single perforator within that territory was calculated from digital an- giograms using Scion Image.Results There were 16 perforators that the diameter≥0.5 ram,20%were septocutaneous,80%were musculocutaneous.Their average external diameter was 0.8 ram.The average ped- icle length from the deep fascia was(3.15?1.43)ram;the perforators from descending branch of lateral cir- cumflex femoral artery walk length average about 2.63 cm in superficial fascia.The area of each perforator supplied blood was average 45.61 cm~2.Conclusion Modified lead oxid-gelatine technique provides high quality angiograms for the study of cutaneous artery and perforator falp.Based on our data,the maximum di- mension of the anterolateral thigh perforator flap can be 30 cm?20 cm in with only a single dominant perfora- tor.The perforator flaps deviced by perforators from the anterolateral thigh are transplanted to the lower limbs and the other part of the body.
